To WTOKOFF, SEAMANS & BENNDICIT : REMINGTON STANDARD TYPEWRITER After using the Remington typewriters in the Vermont Methodist Seminary for more than a year 1 am glad to bear testimony to the excellent results attained. Our instruments are kept in the academic; and pupils who desire are assigned hours for practice. Quite a num ber have availed themselves of the opportunity. I have noticed, first, a care for correct spelling and punctuation which we had not boon able to secure otherwise. I have seeh an unusual attention to the structure of sentences. The rhetoric of composition seems to stand out more clearly before the pupil on a printed than on a written page; and as the manipulation of the machine soon be. comes mechanical, the writer devotes much attention, even in copying articles, to the structure and finish of the sentences. I fully believe that the typewriter put in the hands of all our pupils would prove a valuable aid to their education Send for Catalogue. WYCKOFF.
